Motion reveals Pulse gunman's father was FBI informant

Omar Mateen shot, killed 49 inside Orlando nightclub in June 2016

ORLANDO, Fla. - Attorneys for Noor Salman called for a mistrial after they say new details from prosecutors reveal that Pulse gunman Omar Mateen's father was an FBI source and is currently under a criminal investigation.

According to a motion filed by the defense, prosecutors sent an email on Saturday that stated Seddique Mateen was a confidential FBI source from 2005 through June 2016.

Judge Paul Byron ruled Monday afternoon that the mistrial would not be granted because Salman's attorneys were not harmed by the government's failure to disclose that Seddique Mateen was a confidential informant.

The government email to Salman's attorneys also states that in 2012, "An anonymous tip indicated that Seddique Mateen was seeking to raise $50,000-$100,000 via a donation drive to contribute toward an attack against the government of Pakistan."

According to the motion, the defense states that the decision not to give Noor Salman a polygraph was possibly "based on the FBI's desire to implicate Noor Salman, rather than Seddique Mateen in order to avoid scrutiny of its own ineptitude with the latter."

The defense also said Seddique's connection with the FBI played a role in a 2013 investigation into Omar Mateen for allegedly making threats against coworkers.

“Mateen’s father played a significant role in the FBI’s decision not to seek an indictment from the Justice Department for false statements to the FBI or obstruction of justice against Omar Mateen” during its 2013 investigation into his alleged threats," the motion stated.
